Nelo Angelo is the only Dark Angel in DMC4. He was also referred to as the "Black Angel" in the DMC1 manual. He was a soul attached to armor. There is no one else references in the series by  sinilar name nor whos remains would match the particular type of experiments being conducted.

Its Nelo Angelos remains.
